Pump, inline circulator
Also called circulator, circ pump, inline pump
Service life
Years in service. The band runs from the shortest to the longest life the sources state, so it shows how much they disagree, not how long 80% of units last. The line is the median of the stated lives.

Municipal lives for HVAC (D30)
43 municipalities in Ontario, British Columbia and Alberta state a life for HVAC as a whole, in 35 distinct tables: 10–50 years, median 20. These come from capital asset policies: accounting lives, used for amortization. They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. The dashed line is the median. Policies that copy the same table count once.
